I live in Ciutadella but before me my wife and kids moved here not so long ago we used to go to Cala n porter every year and although we never stayed there we used to go to Bahia park as my sister in law was dating a young waiter there.Food was good entertainment was very good for the kids and it looks really nice,i dont think you made a mistake with this 1.

we stayed here 3 years ago entertainment during day was good on a night unless your kids are under 8 was very boring there is no stage just a small area outside on the side of the bar really quiet place at night so if you are wanting a quiet time youll like it
